I want to print an ebook using Ubuntu 18.10, but instead of a PDF file I have a folder with subfolders (chapters) containing individual jpg images (book pages).
How do I print it on paperback? I thought of somehow combining the images into a PDF file (order matters of course).
Inside the book folder: (using ubuntu Nautilus) https://i.imgur.com/bGnhp8M.png
Inside subfolder: (every subfolder has files with same names) https://i.imgur.com/bGnhp8M.png
